MUKHERJEE IJPRBS-QR CODE PAPER-QR CODE Department of Botany, University of Kalyani, Kalyani, Nadia -741235, West Bengal, India Abstract Accepted Date: 18/03/2013 The tribe Inuleae Cass (sensuMerxmuller et al. 1977) is included under the sub-family Asteroideae of the family Asteraceae consisting of 200 genera Publish Date: and about 2000 species. According to Anderberg (1989) the tribe Inuleae is 27/04/2013 an unnatural, paraphyletic group and he has divided Inuleae into three monophyl etic tribes viz. Inuleae (s.s.), Gnaphalieae and Plucheae. It is also Keywords clear that cypselar anatomical features are of great value for delimitation of taxa in some inuloid genera of Australia by Short et al. (1989). Perusal of Diversity, available literature regarding the exo-morphic features of cypsela in Inuleae Cypsela, shows that the cypselas features play a paramount role for determination of taxa. The present study has been under taken for the detailed study of Inuleae, cypselas in 6 genera and 7 species of the tribe Inuleae. The p resent Asteraceae endeavour is the result of work with 7 species of cypselas in the tribe Inuleae. Among the studied taxa, shape ,size, colour , presence or absence of ribs within the cypsela, number of ribs, thickness of pericarp, ,distribution of surface hairs ,car popodium ; thickness and number of rows of corpopodial cells ; structure , colour and distribution of pappus bristles; cross -sectional Corresponding Author area cypsela and the number of secretary ducts in each cotyledon are Mr.
